The diet and nutrition survey of infants and young children (DNSIYC) 2011 is a one-off survey providing the only source of detailed information on the food consumption, nutrient intakes and nutritional status of infants and young children in the general UK population aged 4 to 18 months. DNSIYC was conducted between January and August 2011. The survey complements the national diet and nutrition survey (NDNS) rolling programme, which covers children and adults aged from 18 months upwards.
DNSIYC involved an interview, a four-day dietary diary, blood samples and estimates of breast milk intake, fluid intake and body composition. Results are used by government to develop public health policy, monitor diet and nutrition patterns and assess whether these meet expert recommendations on infant feeding, diet and nutrient intakes.
